with the wingmaster barrel you can only shoot lead, but if you change the barrel to a slugster you can shoot slugs and buckshot, they also have a barrel for steel shot to.
Yes you can, I own a Remington 870 wingmaster with a 27" smoothbore barrel and it shoots rifled 1oz slugs all day, and fairly accurately. The only thing you cannot shoot through it is sabbot slugs but the nice thing about having a gun like yours is that you can go from slugs to 00 buck shot to bird shot without changing barrels. Good luck and happy shooting
100-400 USD depending on condition.
Depends on how old the shotgun is.
Yes. No problem
Best to get it checked by a competent gunsmith before firing. It might be corroded.
If the gun is marked 2-3/4 on the barrel, that is the maximum length shell that the gun will shoot.
None.
Yes: A Remington 870 shotgun with a modified choke will shoot any commercial shotgun slug.
Yes I own one but you must turn the spring around.
You can, but, it will not be a good thing.

If it's a 16 gauge shotgun, the shell length is 2 3/4 inches.
